LightSpeedRead vs LumaRead

LightSpeedRead is a speed-reading reader that presents words or short groups of words one at a time at a fixed point on screen using Rapid Serial Visual Presentation (RSVP). The web reader accepts pasted text, links, PDFs and EPUBs. Readers can adjust speed, pauses for long words and punctuation, gradual ramp-up, themes, fonts, emphasis and word size. A red letter marks each word’s optimal recognition point, aligned to a fixed center line. Submitting an article URL sends it to r.jina.ai to fetch and extract text; pages behind logins or paywalls may not extract cleanly. Pasted and uploaded text is processed locally in the browser, and the Chrome extension reads page text only when invoked. The free plan includes the website reader and extension reading up to 600 wpm. Pro is $2.99 per month or $19.00 per year, with speeds up to 1000 wpm and additional controls. The iOS app is marked “Coming soon.” The maker cautions that high RSVP speeds can reduce comprehension, especially for dense or important material.

LumaRead is a web-based speed reading app that presents text one word at a time using rapid serial visual presentation (RSVP). It accepts PDF and DOCX uploads and includes a free reading speed test that measures words per minute. The reader removes headers, footers and page numbers, anchoring words at an optical center point; readers can adjust speed, with pacing that responds to punctuation. The free plan saves progress and allows 1,500 words per day, one book in the library and speeds up to 600 WPM. Monthly costs $3.99 a month and allows unlimited reading, 10 library books and speeds up to 900 WPM, with reading statistics. Yearly costs $39.99 a year and adds an unlimited library, custom speeds up to 1,500 WPM, statistics, streaks and priority support. Login, library sync and session statistics require an internet connection. A loaded book can continue in an active session if it remains open on the page. LumaRead can be installed as a PWA for quicker access on mobile or desktop, though the supported platform is web.
